Cognitivism

Cognitivism

Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

Piaget's Theory of Cognitive Development from Childhood into Adulthood

Piaget's Theory of Cognitive Development from Childhood into Adulthood

Jean Piaget's theory of cognitive development emphasizes the role of thinking in a child's learning process, suggesting that children are naturally curious about their environment. His approach to development is discontinuous, proposing that cognitive abilities progress through distinct stages, each with unique characteristics. Central to Piaget's theory is schemata—mental structures that allow individuals to understand and interpret the world.
Schemata: Building Blocks of Knowledge

Storage

Storage

A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze...

Introduction to Cognitive Psychology

Introduction to Cognitive Psychology

Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing.
This field emerged in the mid-20th century, following a period dominated by behaviorism, which...

Collisions in Multiple Dimensions: Problem Solving

Collisions in Multiple Dimensions: Problem Solving

In multiple dimensions, the conservation of momentum applies in each direction independently. Hence, to solve collisions in multiple dimensions, we should write down the momentum conservation in each direction separately. To help understand collisions in multiple dimensions, consider an example.
A small car of mass 1,200 kg traveling east at 60 km/h collides at an intersection with a truck of mass 3,000 kg traveling due north at 40 km/h. The two vehicles are locked together. What is the...

Schemas

Schemas

A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Computational Neuroscience

Background:

Relational knowledge is crucial for flexible cognition.
The neural basis of how the brain represents complex relationships remains incompletely understood.
Previous research has explored spatial mapping but less so the mapping of abstract relational information.

Purpose of the Study:

To investigate how the brain forms unified cognitive maps of relational knowledge.
To identify the specific brain regions involved in integrating distinct relational information.
To elucidate the mechanisms underlying flexible inference based on these cognitive maps.

Main Methods:

Utilized representational similarity analysis (RSA) on fMRI data.
Designed tasks to elicit the representation of multiple, distinct rank orders.
Analyzed neural activity in the hippocampal-entorhinal region and medial prefrontal cortices.

Main Results:

Demonstrated that the hippocampal-entorhinal region and medial prefrontal cortices spontaneously form unified, two-dimensional cognitive maps.
Showed that these maps integrate multiple, distinct rank orders of relational information.
Evidence suggests these unified maps support flexible inferential reasoning.

Conclusions:

The brain constructs integrated cognitive maps to represent complex relational knowledge.
The hippocampal-entorhinal and medial prefrontal cortices play a critical role in this integration process.
This neural mechanism enables adaptive and flexible cognitive inference.
